I have a 2003 Intrigue Sweet Sensation and the water filter is behind a panel on the bay wall next to the wet bay. Remove 6 screws holding the panel and the filter is right there. It's the same as you see in a house, white and about 12-14" tall. I've seen them at Home Depot. I also have weak pressure so I will be changing this filter ASAP. I just bought this coach and the panel was off but when I found several of the screws broken off I just assumed the dealer replaced the filter and didn't put the cover back on. Probably a good idea to replace now since I have no idea how long it's been since it was replaced by PO. Looks like this (not sure if it is this model).
